Minicom doesn't work

Question

I installed minicom and configured it with a usb to serial adapter. When I run minicom with sudo minicom I see only this message : Welcome to minicom 2.7

OPTIONS: I18n Compiled on Jan 1 2014, 17:13:19. Port /dev/ttyUSB0, 10:07:54

Press CTRL-A Z for help on special keys

I should see a Cisco ios. What I can do ?

It seems you cannot input anything on minicom, if that is the case then go in Minicom configuration by:

minicom -o -s

and select the serial port setup option, then turn off the Hardware flow control. I also had software flow control to OFF. It works for me.

May be you can try to use picocom like this:

sudo picocom -b 115200 -r -l /dev/ttyUSB0

with no port reset (-r) and no port locking (-l). Also special keys you can see in the man picocom

You should just press enter. When you start minicom, the login prompt was already issued on terminal and is not displayed again.
If nothing helps make sure you have proper flow settings (in port configuration). For emulation connections like via USB or Ethernet you usually should have both off. Check speed too.

ook I setup the port as ttyUSB0. About speed . What I can do ? you have any values that I can use ? – Daniele Pugliese Jun 19 '15 at 15:00
Speed must exactly match the one that is set on the receiving end. Otherwise you will see only eldritch runes or nothing at all. – Barafu Albino Jun 21 '15 at 11:56

I resolved. If I use picocom with your command doesn't work because the bitrate 115200 is wrong. If I launch picocom with

sudo picocom -l /dev/ttyUSB0

it works fine.

therefore if I change the bitrate in minicom also. It work fine.

finally I relsoved. Thanks so much
